Originally posted by audiobomber 3. Front focussing is directly related to aperture settings. I had no problem with any lens on any camera under any light at F4. At F2.8, I had slight front-focussing under tungsten light. At F1.4, I experienced severe front focussing.
True, and this is largely due the shallower DOF at wider apertures - a slight focus error is going to be much more noticeable if it moves your intended focus point completely out of the zone of acceptable sharpness. and in the case of MF, this is compounded by the fact that the focus screen lies, showing you rather more DOF than will actually be there at wide apertures. So there will always be things in focus in the viewfinder that don't end up in focus in the picture, and on my camera at least, it's the area toward the *front* of the apparently-in-focus zone that end up OOF.
Quote: The allure of super wide apertures is much diminished for me.
I tend to agree, and it's one reason I don't sweat my DA40 being "only" f/2.8. Much wider than that and DOF becomes shallow enough that nailing focus is tricky. But even if AF will always FF in tungsten, you *can* learn to MF correctly. It's simply a matter of learning to put the target toward the very *front* of the in-focus zone in the viewfinder, rather than towards the rear. Takes practice to learn to focus this way, but it can be done.
